This invention relates to a vaporizer and supercharger for internalcombustion engines, the general object ofthe invention being to providemeans for heating and theroughly vaporizing the'exp'losive mixture as itpasses from the carbureter to the cylinders so as to greatly increasethe efficiency of the engine by increasing therombustibility of thecharge, greatly increasing the miles per gallon, preventing overheatingof the engine and otherwise securing the maximum efficiency 'with theminimum amount of fuel.

This invention also consists in certain other features of constructionand in the combination and arrangement. of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in *detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is anele'v'ation'of an engine, showing the invention applied thereto.

Figure 2 is a'top plan view.

Figure 3 is a front view. 7

Figure l is a section on line H of Figure 2. t

Figure 5 is a section on line 5--5 of FigureB.

In these views, the numeral 1 indicates a tank suitably attached to theengine, preferably 011 the top thereof, and provided with a fillingopening '2 closed by a cap 3, so "that the tank may be filled withwater. The tank has a cylindrical bore 4 passing thereth-rough, the endsof whichare closed by the'covers 5. A shaft 6 is journaled in thecovers, with the front end of the shaft projecting, and this projectingend has a pulley? thereon which is adapted to be connected by a belt '8with a pulley 9 on the fan shaft of the motor. Spiders 10 are connectedwith the shaft and are located adj acent the ends of the bore and a fan11' is connected with the shaft and is arranged at the center of thebore. A perforated cylinder 12, preferably formed of wvire mesh, isconnected with the spiders and fan and 'aspira'l 13, formed of wiremesh, is

connected with the shaftand'the cylinder 12 on each side of the fan 11.Battles 14, also formed of wire mesh or gauze, are connected with theshaft and cylinder and are arranged between the convolutions of thespirals.

Thus the cylinder 12, the two spirals .13, the

baffles 14 and the fan all rotate within the bore of the tank with theshaft.

A pipe 15 connects a port 16 in the front cover 5'with the carbureter 17and a pipe 18 connects a" port 19 in the rear cover 5 with theintakemanifold 20 so that the mixture from the carbureter passes throughthe :pipe 15 into the port 16 into the bore of the tank, where'it issubjected to the rotative action of the spirals and fan and thus forced'A small cylinder 27 is connected with the top of the tank and is incommunication therewith through the port 28 and a piston 29 is arrangedin the cylinder and is normally pressed against the port carrying part28 by a spring 30. Thepiston rod 31 is connected with a lever 32 whichin turn is connected by a link 33 with the arm of the valve 24, theseparts being so arranged vthat as the piston 29 is forced upwardly by theexpansion of the hot water or steam in the tank, the lever and link willcause the valve 24: to close-and thus vprevent the exhaust gases from Ipassing through the pipes in the tank. Thus these parts act as aregulator for controlling the temperature ofthe water in the tank,,-foras soon as the water reaches a-certain degree, the valve 24 will closeand thus prevent the exhaust gases from passing through the pipes in thetank to prevent t'hewater from being overheated. As soon'as the watercools, the piston will drop and the valve will open again so that theexhaust gases will again flow through the pipes in the tank.

A vent 34 is formed in the cylinder 27 and if the water in the tankshould become overheated through failure of the valve operating means tooperate for any reason, the pressure in the tank would cause the pistonto pass above the vent and thus steam or water would pass through thevent so that this vent and piston acts as a safety means for preventingoverheating of the water in the tank if the other means should fail tooperate.

From the foregoing it will be seen that I have provided means forheating the explosive mixture as it passes through the bore of the tankand the rotating cylinder 12 and its associated parts will thoroughlymix the charge as it passes through the device and any drops of fuelwill be broken up. The mixture is first operated on by the first spiral13 and then the mixture is acted on by the fan 11 and after passing thefan, the mixture is acted on again by the second spiral. The

mixture is caused to pass through the perforations of the spirals andthe bah-es so that it is thoroughly mixed and vaporized and as thecylinder 12 is formed of foraminated material, the mixture can passthrough the same and thus come in direct-contact with the hot walls ofthe bore forming part l. Thus the mixture is thoroughly agitated, solidportions broken'up and mixed with the air, the mixture is heated and themixture is forced by the rotating parts into the pipe 18 through themanifold into the cylinders. Thus the mixture reaches the cylinders ofthe engine in a highly explosive condition, so that the engine willstart quickly, and the greatest amount of efiiciency is secured with theminimum amount of fuel. -As before stated, the temperature of the waterin the tank is automatically controlled and safety means are provided ifthe controlling means should fail to act for any reason.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent. 7

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.
